The National perform "Don't Swallow The Cap" on Letterman

Before today's release of the super-anticipated Trouble Will Find Me, The National hit last night's Late Show with David Letterman to perform the LP's early standout "Don't Swallow The Cap".

Last night's live version featured a ring of string and complimentary horn pieces, as well as Doveman, aka Thomas Bartlett coming in on keys, making for a fairly grand performance. Watch the whole thing below, and grab Trouble Will Find Me today(!) on 4AD.

Bonus: The National just announced the band will be performing with Dirty Projectors June 7 at the Mann Center in Philadelphia. Tickets for the event will start at $39.50, and will be sure to sell out quickly.
